3 Claims.

Our invention relates to storm window constructions which are removablyattachable to standard or slightly modified window frame structures.

An important object of our invention is to provide a window constructionwhich is light in weight, rigid, strong and durable in constructionwhich has a storm window sealably secured therein, and which isattachable from the inside of a building, as distinguished from presentstorm windows which are attachable to the outside of the building.

Another important object of our invention is a to provide a storm sashstructure which is securable to a window frame from the inside of abuilding structure.

Another object of our invention is to provide bolt locking means whichmay be set to operative and inoperative positions in order to facilitatethe insertion and removal of the storm sashes or windows.

A further object of our invention is to provide a bolt and lockmechanism which will permit snapping storm sashes into engagement, andwhich is settable so as to permit removal of the said storm sashes bysnapping them out of engagement; thus facilitating insertion and removalof sashes, which is even more so simplified by virtue of the fact thatthe said storm sashes are insertable from the inside of the buildingstructure.

A still further object of our invention is to provide storm sashstructure of the aforementioned character which is simple and durable inconstruction, sealable against the elements, one which can be insertedor attached from the interior of a building structure, and which is ofsuch elemental construction as to warrant economical manufacture thereofin quantity production.

Other objects and advantages inherent in our invention will becomeapparent from an examination of the accompanying drawings, elucidatedfurther in the ensuing description, wherein like numerals designate likeparts and in which: Fig. 1 is a perspective view of a pair of windowframes to which our invention, the storm sashes, have been attached.

Fig. 2 is a longitudinal, cross-sectional view taken substantially onthe lines 22 of Fig. 1.

Fig. 3 is a perspective view of an individual window frame with its ownstorm window pane therein, showing the storm-sash comprisingcurinvention in the process of being attached there to, or removedtherefrom.

Fig. 4 is a perspective view of an individual storm sash constructionmade in accordance with the practices of our invention.

Fig. 5 is an enlarged front view of one of the locking bolt mechanismsutilized in securing the storm sash, comprising our invention, insnapping engagement, being a view looking in the direction of arrows 55on Fig. 2.

Fig, 6 is a cross-sectional view taken substantially on the line .66 ofFig. 5.

Fig. 7 is a transverse cross-sectional view taken substantially on theline 1-1 of Fig. 6.

Fig. 8 is a transverse cross-sectional view taken substantially on theline 8-8 of Fig. 6.

Referring to the various views, our storm window invention is generallydesignated 9 and consists of a slightly modified window frameconstruction In which is suitably rabbeted as indicated at H in order toreceive snugly the sash frame designated l6 shown in detail in Fig. 4.

It is to be noted that the lower portions of the window frames at l2 andI3 are suitably grooved in order to receive the tongue-like portion I!on the storm sash [6. The groove is wider at the top to permit insertionwith, and removal from, of the storm sash with respect to the windowframe defining bearing surface 46 for the ledge 45 to rest thereon, andrender the assembly rattle-proof. At each of its sides and preferablynear the upper portion thereof, mortised portions 18 are provided, whichare to be engaged in snap-on and off relationships by the bolt structuregenerally designated [9.

Finger cut-out clearances l4 and 15 are provided so as to facilitateremoving the storm sashes from the windows whenever removal becomesdesirable or necessary.

Storm sash structure [6 is made preferably of a light aluminum ormagnesium metallic material, of channelled cross-sectional configurationdesignated 20, having sealed thereinto the glass pane 2! by means of achannelled resilient structure 22's0 as to form an adequate seal againstthe elements, and at the same time maintain the storm sash rattle-proof.I

The details of the bolt-locking means are indicated in Figs. 5-8 whereinit can be seen that the bolt-locking structure l9 consists of a body 23having a bored out cavity of cylindrical formation 25, for purposeswhich will later appear, being also provided with a slotted portion 38atthe top thereof in order to permit the manipulating knob 35 to beoperated therein; ,the said knob 35 projecting above the slot 38. Thebody 23 is secured to the face of a window frame by screws 24 or otherdesirable fastening means.

Within the cavity 25 is mounted a cylindrical sleeve 34 which isprovided with a spiral cam groove 36 extending over 180 degrees of itscircumferential configuration and substantially throughout its length.

The knob 35 has a protuberance 39 which operates in the said cam groove36; the knob sliding from left to right, to the dotted position, willcause the said tubular sleeve to rotate 180 degrees. Within the saidtubular sleeve is mounted; a spring 33 coiled about the reduced body ofthe bolt 32 which has an enlarged portion 3| provided with a titoperating within the slot 36 of the tubular structure 34.

The enlarged portion 3| is cylindrical in construction and is providedwith a bolt portion 21 and an angular cam portion 28.

The sleeve 34 is provided with a slotted portion 26 toreceive the tit orprojection 38 to operate therein when the bolt 3! is cammed backwardlyagainst the tension of the spring 33 confined in the cylindrical bore 3!thus normally maintaining the same outwardly.

The window sash at the mortised structure is provided with the roundededges 29 which will efiectively cooperate with the cammed surface 28when the same is either in the position shown in full lines, which isarranged to receive the sash in snap-on relationship, or when the knobis moved to the dotted position, to the right, thus rotating the bolt180 degrees, and placing the cammed surface 28 in the dotted position soas to permit disengaging the sash [6 by a snap-off action.

Thus it can be seen that the storm windows and the bolt-locking meanstherefor will facilitate the tedious task formerly employed in attachingstorm windows on the exterior of a building thus eliminating caulkingand such other laborious tasks for weather-sealing purposes-- so vitalto a construction of this type.

The window frames 10 will operate in the same normal manner, they willnot interfere with the sash structures assembled thereto and may beopened or closed as desired. Likewise, when the storm sashes 16 areremoved the windows will be in the same condition as they were beforeattachment of storm sashes and be ready for the summer, or springseasons.

In connection with our construction, it may be advisable to improve thisarrangement by placing the customary window screen in locked position inthe sash frame of the window, below the lower edge of the upper window,thus furnishing a complete combination storm and screen retaining unit,which need never be changed; the storm sashes may remain in assemblypermanently, since ventilation can be obtained through the screen placedunderneath the upper window at the lower edge thereof, contiguously orbehind the lower window and to the left thereof when viewing Fig. 2.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.

Having thus disclosed and revealed our invention, what we claim as newand desire to secure by Letters Patent is:

1. In combination, a window frame having a rabbeted portion on. threesides of the internal perimetral portion thereof and a channelledportion on the bottom side, the said channelled portion being enlargedat the top portion, the channel being enlarged substantially at its topsurface to define an adjacent bearing surface, a storm sash fittedremovably within the said rabbeted portion and provided with an oifsettongue portion defining a ledge portion locating and engaging itremovably with respect to the said channelled. portion, the tongueportion being sized to fit the channel sufficiently that the said ledgeportion rests on the said bearing surface.

2. In combination, a window frame having a rabbeted portion on threesides of the internal perimetral portion thereof and a channelledportion on the bottom side, the said channelled portion being enlargedat the top portion, the channel being enlarged substantially at its topsurface to define an adjacent bearing surface, a storm sash fittedremovably within the said rabbeted portion and provided with an offsettongue portion defining a ledge portion locating and engaging itremovably with respect to the said channelled portion, the tongueportion being sized to fit the channel sufficiently that the said ledgeportion rests on the said bearing surface,
